Read the Opponent’s Spin
All high-balls should not be smashed in the same manner. When you see a high topspin ball, step back slightly, start your racket high, and smash forward and down. When you see a high backspin ball, step forward, start your racket lower and the angle more open, while smashing forward and slightly up.

Add Spin to Your Smash
A smash with some topspin will possibly be 10% slower, but it will usually have about 50% more control. Be consistent in smashing – add topspin!

Place Your Smash Correctly
When your opponent is near the table, smash to his elbow (his transition point). At the transition point, he will need to make a very quick decision to use backhand or forehand. When he is away from the table, smash more often to the wide angles – especially the wide backhand. When your opponent is far from the table, the court becomes wide. In order to cover the wide angle, he will be forced to move 15-20 feet to reach the angle balls.
